Application filed February 1, 1909. serial No. 475,516.

To all whom it may concern:

Be it known that I, HENRY HOWARD, a citizen of the United States, residing at Boston, in the county of Su'flolk and State ofYMassachusetts, have invented certain new and: use ful Improvements in Liquid-Flow Indica- The object of this invention is the provision of a simple, reliable and inexpensive device for visually indicating the How of liquids. g

It is often desirable to provide means permanently connected in a liquid conduitor circulating system for indicating or measuring the rate of flow of liquid therein and for" adjusting such flow with accuracy to a desired or predetermined standard. This I 2.0- complish by means of the apparatus shown drawing wherein: central vertical section of a. preferred form of apparatus; Fig. 2 is a. ver-; tical sectional view of the standard on am enlarged scale; and Fig. 3 is an elevation. of the standard viewed from the discharge side..

Referring to the accompanying drawing, E represents a cup-shaped base orliquidreceptacle which may be of cast iron or of such metal or material as Figure 1 is a uid. A glass bell-jar 2 stands within this receptacle and rises above the upper thereof. An inflow pipe 3 and an outflow i pipe 4 for liquid communicate with the interior of the receptacle 1 through 1ts bottom. The outflow pipe i may pro ect upwardly into the receptacle as shown at 5; this an rangement is particularly useful when the liquid is volatile or is accompan ed by gases, as a liquid seal is thereby provided to prevent the escape of gas around the bottom of the bell-jar. r

A standard 6 extends upwardly within the .bell-jar in communication with the inflow pipe 3. As shown in Figs. 2 and 3 this standard comprises a pipe, which may be open atits-upper end, and is'provided with a series of lateral discharge orifices 7, uniformly spaced. Preferably suitable lips 8 are arranged in connection with the several discharge orifices as shown In order that the flow from each may be clearly seen. This standard will of course be constructed of a material unacted upon by the liquid flowing through it.

This indicating device may be connected through, it being necessary merely extending upwardly aboaze the top of the standard 6, ;miriating in a funnela 131 for receiving the. liquid. from the cock 1 may be required to /withstand the action of any particular liq-- .30 liquid receptacle,

5 duits; communicating; therewith, a fixed "in any liquid conduit, and serves as a ready means for indicating the flow of liquid thereto note the number of discharge orifices through which liquid flows. Suitable valves or other Z controlling devices are provided in the liquid tors, of which the following is a specification.

to establish conduit, the operator being thereby enabled a flow through one or any desired number of the orifices 7 as may be desired. The rate of flow-through 611e, two, etcz, orifices may be measured, and recorded if desired. in a tabular statement attached to the device, which; then becomes a measuring, instrument for thisparticular liquid question or one having physical properties. In case the flow of liquid is substantially constant theiiiidiieating device: may be directly connected int thesystem and the flow therethrough controlled; in any manner. Amy desired means; tor equalizing; intermittent or irregular! flow! may oi coursebe: employed. Thus in: Fig 1 I havejiillnstrated. the inflow pipe 3 as connected with. a leg 10 outside the; hell-j at this leg ter- Iclaim: p 1. A liquid-flow indicator comprising a inflow and outflow 0011* standard extending upwardly fiom the inflow conduit, said standard having a plurality of lateral discharge orifices for the liquid disposed at different levels and an outflow conduit below said discharge orifices.

' 2. A liquid-thew indicator comprising; an open-topped receptaclefor liquid, inflow and outflow conduits communicating therewith, a standard connected with the inflow conduit,

lateral discharge orifices for the liquid disposed at different levels,

and a transparent casing inclosing said standard and outflow.
